German Glock, 27, had been linked with a move to Renault next year, but earlier this week he insisted that despite having "several options" with "more established teams", he chose to be part of "building a team" from scratch.

Niki Lauda has questioned Timo Glock's claim that he chose to switch to the new Manor/Virgin team for 2010 even though he had other options.

German Glock, 27, had been linked with a move to Renault next year, but earlier this week he insisted that despite having "several options" with "more established teams", he chose to be part of "building a team" from scratch.

Triple world champion Lauda told Germany's Auto Bild: "I can only imagine that Manor was his only chance, otherwise the choice was a mistake."

Lauda, 60, said moving to an existing team would have been a better idea.

"Nobody can really judge which of the new teams can do a good job. I have therefore no idea why Glock did not see through his opportunities with Renault or the Sauber/Qadbak team," he added.
